English term or phrase:acceptor
Definition from Tyco Electronics Corporation: A material that is intentionally added to a pure semiconductor material to increase the population of free holes in that semiconductor, resulting in a net positive charge. A semiconductor that has had acceptor material added to it is called "p-type."
For practical doping levels, it is fair to assume that the free electron concentration is equal to the concentration of donor atoms and the hole concentration is equal to the concentration of acceptor atoms. everything2.com
Acceptor dopant in nitride semiconductors makes deep acceptor level (>100 meV) and generates few hole carriers into the valence band because of large electron affinity of N. Materials Research Society
The energy gained when an electron is taken up by an acceptor atom from the valence band of the crystal is the ionization energy of the atom. answers.com
De acord cu traducerea „acceptor”.
ACCEPTÓR, acceptori= atom trivalent care introdus într-un semiconductor primește electroni de la un atom din rețeaua cristalină a acestuia (sursa: Dex )
In Dictionarul tehnic EN - RO (Ed. Tehnica): acceptor = acceptor, atom cu invelisul electronic incomplet.
După felul impurităţilor pe care le conţin, semiconductorii extrinseci pot fi: donori, dacă impuritatea are valenţa mai mare decât cea a semiconductorului; acceptori, dacă impuritatea are valenţa mai mică decât cea a semiconductorului. - Wikipedia
Explanation: Sunt inginer electronist de peste 30 de ani şi termenul face parte din vocabularul meu curent încă de pe băncile facultăţii.
